Guozijian has always been the most deserted Banshan Hall, and this day began to be lively from early in the morning.

Some of the prisoners, who had hardly been seen in the past, came from far and wide by cart, horseback or pannier, and then whispered in small circles in the past, and finally entered the hall in a chaotic manner after the door was opened.

When I found that there was a person's name on each table, some people inevitably complained, but when I wanted to change the seat, I found that the person's name was engraved directly on the table, and if I wanted to change the seat, I had to move the table. In addition, Zhang Chen took Zhang Wu and Zhang Lu around like a patrol of the sea, and the disciples could only sit down helplessly according to their seats and names.

When everyone was almost seated, two children, apparently no more than seven or eight years old, suddenly appeared at the door, probing their brains there. Seeing this, the sharp-eyed Zhang Wu hurriedly coughed lightly: "Are those three princes and four princes at the door?" ”

His voice was neither light nor heavy, and after a while, the huge half-mountain hall fell silent. It's not that the two young princes have much deterrence, it's because everyone is worried that the emperor has sent someone to escort them, and they will be responsible for observing the behavior of the others when they go back. When they saw that the two little guys who were very short were still hesitating outside the door, someone couldn't help but sneer.

"The prince is here, but the gentleman hasn't come yet, it's a big shelf...... Belch! ”

The next moment, he saw a person suddenly inserted between the two princes, and then pulled one with one hand, gently but toughly brought the two little guys into the mid-mountain hall.

After sending the two of them to the only two seats in the first row and settling down, the man who had just led them in slightly bent over straightened up. I saw that he was sixteen or seventeen years old, wearing the official uniform of Dr. Guozi in cyan color, with extremely outstanding facial features, smiling faintly at this time, his eyebrows were sparse, handsome and amiable, and at first glance he seemed to be a gentle and easy person to get along with.

And as the people came to the middle station, everyone understood that it was Dr. Guozi, who was known as the youngest doctor in the history of Guozijian, and Zhang Shou, who would control them to death from now on!

"It looks like it's full. Then I will take a roll call, and I will stand up and introduce myself to everyone. For example, my name is Zhang Shou, and I'm best at things related to numbers, and so on. Of course, if you don't feel that you have any advantages, it doesn't hurt to say what you like. For example, my favorite thing is to go on a safari on horseback. ”

After Zhang Shou finished speaking, he didn't pay attention to the whispers under his head, let alone turn over the roster, and called casually: "Zhang Chen." ”

After discovering that Zhang Shou had come in, Zhang Chen, who was in the second row behind the third prince, immediately stood up. Of course, he will not be stunned at all about self-introduction, and even proudly turned his head and glanced around at everyone, and then said word by word: "I am Zhang Chen, the eldest son of the Duke of Qin, and running horses and archery can only be said to be so-so, but beating people is by no means ambiguous!" ”

He deliberately accentuated his tone, so that the third prince and the fourth prince, who had grown up together, couldn't help but exchange glances, and at the same time decided that Zhang Chen was a dangerous person!

And Zhang Wu, who was named by Zhang Shou next, spoke very gently: "I am Zhang Wu, the son of the Marquis of Nanyang, and I have no specialty, that is, meticulous patience is still a strength." Well, I like to write, and I'm good at calligraphy. ”

"I'm Zhang Lu, the son of the Marquis of Huaiqing, I'm a person, I can talk to anyone, but it's a pity that I wasn't born in the Spring and Autumn Period and the Warring States Period, otherwise I must be a top strategist." Zhang Lu was much more exaggerated than Zhang Wu, and arched his hand in all directions with a smile, "In the future, classmates, please take care of me!" ”

With these three people as examples, plus the third prince and the fourth prince were still sitting in front, when someone turned his head to look at the door, he also peeped over there in addition to the guards standing like piles, and other officials of the state prison seemed to be observing, but they didn't dare to be too presumptuous, introduced themselves calmly, and casually talked nonsense or two, and after about two quarters of an hour, this scene was over.

It was only at this time that Zhang Shoufang smiled and said, "Very good, please ask the third prince and the fourth prince to talk about it too!" ”

was suddenly named, and the third prince was suddenly a little caught off guard, however, seeing Zhang Shou smiling gently, he thought about it, and finally stood up and said, "I am Zheng Rong, the third prince." I'm good at...... Well, draw! My father also praised me for my talent! ”

And the fourth prince probably because he had his brother as an example, and he answered even faster: "I am Zheng Qiang, the fourth prince, I am very good at chess, and my father has lost to me!" ”

As soon as these words came out, the hall was full of laughter for a while.

Everyone knows that the emperor is a stinky chess basket, and now that he hears that the dignified son of heaven can even lose his son who is only seven or eight years old, how can he not laugh? After the laughter, the Banshan Hall was silent, because everyone thought of the consequences of laughing at the emperor...... Isn't this looking for death?

Seeing that the fourth prince's face turned red with anger because of the laughter of others, Zhang Shou secretly sighed that he threw two children who were only a little bit old and a group of half-grown teenagers into a piece of free-range, I really don't know how the emperor's heart grows. Moreover, these two princes don't seem to have the natural arrogance of the dragon son and phoenix grandson, but are a little naïve and simple.

So, he immediately smiled and exclaimed: "At the age of the fourth prince, if you can really win against the emperor, it shows that your chess talent is indeed excellent." Playing chess is about the way of vertical and horizontal, the way of vertical and horizontal lies in calculation, as long as you study hard in the country, maybe in the future, you will not only win the emperor once or twice, but also become a generation of national players. ”

The fourth prince's face suddenly lit up, and the joy couldn't be covered, where was the appearance of being angry just now?

And Zhang Shou looked at the three princes with a smile and said: "If the third prince is free in the future, you might as well bring the painting and let everyone appreciate it." ”

"Good!" The third prince's eyes suddenly lit up, and he almost didn't immediately run back to the palace to get his painting.

As the two princes who are in the back of the order, they are not far away from the emperor like most of the princes of previous dynasties, but they will be called to the Qianqing Palace whenever they are free, and the emperor will either play chess with them, or watch them paint, and treat them very closely.

Moreover, one of their mothers died early, and the other was born in the folk and had a delicate temperament, and the people around them were all carefully selected by the emperor himself, and they were immediately transferred away if there was a hint of something, so they were raised like a folk boy, quite a little naïve. At that moment, the two of them felt at the same time that Zhang Shou was quite interesting.

And Zhang Shou, who they thought was quite interesting, came up with something more interesting next.

"The Jiuzhang Hall has not yet been repaired, and the Taizu inscription plaque has not yet been hung up, but I think you have all heard of the public case of the inscription. The merits aside, why to judge whether the plaque is hollow or not, I can't demonstrate it live now, so there's nothing to say, but I've used this to explain the principles of the world to a few old adults, and I want you to see the same method today. ”

As he spoke, Zhang Shou poured a small bag of rice on the table, and then inserted a chopstick into it, only to see the chopsticks swaying twice, and finally fell unsteadily on the table.

Seeing that most of the people were puzzled, and some people were full of disdain, he took out a porcelain cup, poured a pinch of rice into it, inserted the chopsticks into it, and compacted the rice. Faced with this scene, the other people's reactions were acceptable, but the third prince and the fourth prince were immediately stunned.

"Can anyone tell me what to do with this scene in front of me?"

As soon as the words fell, Zhang Wu was the first to stand up and speak loudly: "The teacher wants to teach us that if everyone is united, we can move mountains and seas, and we can do anything!" ”

Belch...... The associations of liberal arts students in these years are really rich......

Zhang Shou only felt that he couldn't cry or laugh, still holding the cup of rice with chopsticks in one hand, and motioned for Zhang Wu to sit down with the other hand, and saw that the others did not mean to speak, so he smiled and said: "What Zhang Wu said, at most, can only be regarded as an extension, the actual situation is that after the rice grains are compressed, there is friction between the rice grains and the chopsticks, and the friction is greater than the weight of the rice and the cup, so the cup will not fall." ”

"What is friction? When your hand rubs against a table, an armrest, anything, you can feel a kind of resistance, and this thing that prevents you from moving, or is about to move, is friction. ”

Immediately after, he didn't care what the expressions of the people below him were, whether he could understand it or not, he took out a piece of paper casually, turned around and pasted it on the wall behind him, only to see it fall to the ground suddenly. He bent down to pick it up, laid it flat on the lectern, and brushed it over and over again with the shaft of a brush, then picked it up, turned around and stuck it on the wall again.

This time, the white paper was stuck to the wall as if it had been spelled.

"It's sticky!" The fourth prince almost jumped up and shouted loudly, "Is this a trick? ”

"No, it's not a trick, that's the way the world works." Zhang Shou smiled at the four princes, and when he saw people, he was shocked, and sat down in a hurry, he said lightly, "This can't last, after a while, this piece of paper will fall down, because of the static electricity generated by the friction between the brush and the paper just now, which makes it adsorb to the wall." ”

"There are many truths in this world that are not easy to discover, but there are also many truths that you will take for granted when you read them. When the fruit is ripe, why does it fall from the tree? Why does water flow from high to low? When boiling water in a pot, how powerful will the boiling steam be if you press a heavy object on the lid of the pot? Why do you always see lightning and then hear thunder? ”

Compared with the boring preaching of the sage book that everyone originally thought was boring, Zhang Shou came up with two strange little experiments, and then asked why, which immediately attracted a lot of people to whisper, especially the third prince and the fourth prince looked at each other excitedly, and they all felt that this teacher was more interesting than they imagined!

"The principles of the world are broad and profound, which is also the reason why Emperor Taizu set up many subjects such as arithmetic and gewu. However, those difficult avenues are too unfriendly to ordinary people, so they are not suitable for the vast majority of people to study in depth, but they must not be known. Reverence for the way of heaven, worship for the sages, and the pursuit of the principles of the world are not contrary. ”

"Why are you nobler than a peddler's pawn? Not just because of the illustrious origin, not just because of the wealth of the family, the real nobility lies in the fact that you know more than them and see farther than them. When a single creation of your ingenuity, a decree that you painstakingly solves, can change the lives of ordinary people and make them better off, that is true nobility. ”

"Suiren makes fire, Cangjie makes words, and Shennong distinguishes medicine...... Papermaking, design of agricultural tools, water-making ...... It is precisely because generations of noble sages and former sages have found out the truth of the world from one after another that this is the life of today's people. Throughout history, it is the people of the world who are gradually understanding the principles of the world, and life is getting better and better day by day! ”
